Yes. You are right, the governments of some countries are very hostile to bitcoins. But I want to believe that they will change their attitude to the cryptocurrency. But the fact that bitcoin will replace the dollar is still too early to say
Even with the positive view of other country to bitcoin, it will never replace dollar anytime soon. Even the etf were not approved by SEC, what more being an official currency of one country. Bitcoin is always best being an alternative currency to USD.
Well, you are right about that. I mean, people already use dollar currency since long time ago and bitcoin is not popular as dollar. I think it's hard for bitcoin to replace dollar, people need to know what and how is bitcoin works to get accepted by people and bitcoin don't have a physical unit like paper or coin.
It is not just hard but impossible to happen. Within its lifetime bitcoin could not replace dollars or any of the fiat currency. The basic reason is that the government will not allow it since bitcoin is out of their control and the second is that even if they will adopt bitcoins the total number of bitcoins in the circulation cannot cope up with the actual number of fiat currency in the entire world in circulation.
